Unfortunately, despite what many companies write in their manuals and what you all expect they will hang you on your EFIS wind
Warsaw - Luftansa A320 Accident

The crew did not turn to account the wind display on EFIS and did not consider the discrepancy between these data and the information on the wind given by air traffic services. They neither did take into account that tailwind component displayed on EFIS exceeds the value defined by OAM as acceptable for this aircraft.
There is a fantastic book which would shock many called "Air Law for Commanders and their Crews" - it's based on case law i.e. what will apply in court if you have an accident - unfortunately, long out of print.
